Key Features & Specifications
-
21mm Size & 1/2-Inch Drive: Standard sizing widely used across automotive wheel nuts, lug bolts, and various heavy mechanical chassis fasteners on cars, vans, and light commercial vehicles.
-
6-Point Single Hex Design: Maximizes surface contact on fastener flats rather than the corners, eliminating slip and preventing damage or rounding on stubborn, rusted, or high-torque bolts.
-
Drop-Forged Chrome Molybdenum Steel: Built from high-strength alloy steel engineered to absorb extreme impact shocks and torsional stress without cracking or shattering under power tool use.
-
Corrosion-Resistant Black Phosphate Finish: Treated with a rugged industrial coating to repel workshop oils, grease, and moisture.
-
Pin and O-Ring Retention Groove: Includes a drilled base hole and exterior groove for secure locking pin and rubber O-ring retention when used with heavy-duty air or electric impact wrenches.
